Multiple instances of Unified Power

[LoneWolf]

Is there any reason a character cannot have two or more separate sets of powers with taking the unified power limitation?  Each set would only be affected by drains targeting powers in their own set.  For example, a character with both fire and ice powers is hit with a drain that affects one of his fire powers so drains all the fire powers, but none of the ice powers.

Apart from GM restrictions, the rules allow for multiple instances of Unified Power (multiple sets of Powers, minimum of 2 in each set).
